It could be that the MAF is faulty? Or the wiring is damaged or it may be nothing to do with the MAF, you’ll have to check all the possible causes one by one.

Air leak after the MAF maybe?
Check the things mentioned in the Ross-tech wiki, google will help you with guides on how the trouble shoot each one if you need a bit of direction.

That's probably for intake valve cleaning...I have a DIY for this, but I just use a '4-parts fuel:1-parts solvent' solution rather than a canned product after looking at multiple MSDS's for each product: https://www.youtube.com/watch?v=fy53uOVeSKw&t=95s
...will it help with your current problem? Depends, although not likely to. Build-up can be so bad it may cause misfires, but not the lean condition as it restricts airflow.

Make sure everything’s tight from intake (after MAF) to PCV, check plugs are tight enough and coils are down and plugged in properly to start and clean your MAF and make sure she’s plugged in. Could also be injectors, fuel pump, exhaust leak...Check it all bro!

For the most part I got by this guide...

Upon further diagnosis, I have concluded that I have a ruptured rear main seal. Oil is leaking from the space between engine and transmission. I am throwing all the same codes that this problem causes and This would explain the pcv issues. I consider myself handy but i will not be able to do this myself. total costs are going to be in the 700-900 range even though it is a 30 dollar part. thanks for the help everyone.

I have just had the rear main on my GTI replaced due to a failed PCV, I did NOT have any codes, the rear main failing is caused by the failed PCV not vice versa! There is a VERY VERY recent new revision for the rear main, I’ll get you the part number in a bit, you must make sure it is fitted correctly as it is fitted differently to the old revision,

Rear main p/n - 06K103171G, I don’t know if your MT or DSG but I had the flywheel and clutch changed while it was apart, the flywheel as it has to be removed anyway and the clutch as it had oil on it!
